I'll be on the return leg of a long-haul round trip in a few days. This trip is my first experience with angled lie-flat seats and sleeping at an angle proved a challenge...
If you have successfully slept -- or at least made yourself comfortable -- on angled lie-flat seats, please share your experience...I'd love to have a better flight

On AAs next generation biz class seat which is angled I haven't had any sliding problems that some people report. Basically I but it in almost lie flat its just about in a very flat cradle position. In the fully flat position it seemed as though there was too much lumbar on the lower back so raising the seat slightly did the trick. Hope this helps!

I think peoples experiences on sloped beds depends on what sort of sleeper they are.

Friends of mine who are , for want of a better word "tranquil sleepers" seem to be fine whether it is sloped or true lie-flat , on the other hand , I am quite restless , and inevitably in the process of tossing and turning I move down the slope at least on the old style QF sloped Skybed ( I think my record was on JNB-SYD where I woke no fewer than 4 times to find myself in a little heap well downhill from where I had started - it wasn't too big a deal , each time I just pulled myself back up to the starting position and went back to sleep - but it definitely was a broken sleep compared to what I get on a lie-flat where I am dead to the world and usually have to be shaken awake for brekkie ) and LH sloped bed in contrast to the true flat of EK and NZ where I have no problem .

No problem sleeping in AA business class. Always go to sleep while watching a movie or program. Never had a problem sliding out of the J bed. After years of flying Y on those birds, now I kind of like them a lot, as it is completely different to being in the back of the plane.

I recently had the fully Lie-Flat seat on LAX-ATL on the Delta 777-200LR, and I actually found THAT awkward for sleeping because most of the flight, the aircraft was at a slight nose-up angle, and in the fully flat position, my feet were above my head. I slept with the seat almost fully reclined but not in true flat mode. (Granted this was not long haul or even a redeye).

Quoting warren747sp (Reply 9):U can't do it. U are better off flying an airline which offer as close to a true flat bed as possible.

Depends. I've seen some airlines have "176 degree recline". If the airplane is nose-up 2 or 3 degrees, than 176 degrees moves closer to 180 degrees and is essentially "flat", where as with true 180 degree recline, your feet are now above your head at a 2 to 3 degree angle.
